Abstract

The present invention relates to an electric dredging appliance for sewers of sinks, which is characterized in that the electric dredging appliances for sewers of sinks is provided with a movable blade A and a static blade B. The number of the static blade B is much larger than that of the movable blade A. The movable blade A and the static blade B are arranged around a cavity 2. The electric dredging appliance for sewer of sink can quickly cut and crush the discharged massive waste discharged by the waste water, such as the rotted potato, big vegetable leaves, etc., and can prevent the pipeline of the sink from being blocked. The electric dredging appliance for sewers of sinks is suitable for hotels, restaurants and the dining halls and can guarantee that the pipeline of the sink is unblocked.

Description

Electric dredger for washing sink

The present invention relates to a kind of device that helps to get rid of obstruction in waste pipe or the pot sink.

For preventing that waste pipe from stopping up, way commonly used is to stop refuse to enter waste pipe, places filter screen at the entry port of waste pipe, allows refuse heap on filter screen, by the artificial conglomerate of in time removing on the filter screen; Secondly, before waste water is put in stranding, artificially the refuse in the kitchen sink is picked up otherwise processed one by one, refuse in the minimizing waste water such as rotten vegetable leaf etc. enter waste pipe, otherwise stopping up appears in waste pipe easily, influences discharge of wastewater, and it is quite time-consuming bothersome manually to dredge waste pipe.Chinese patent CN91202750.9 provides a kind of electrodynamic type service sink dredging device, by fixedly baffle ring, knive-edge blade drainage fan, support, motor etc. constitute, fixedly baffle ring is by stent support, arrange near the cloth discharge ends mouth, sheet draining fan is near fixing baffle ring during knive-edge, be connected with the electric machine main shaft of below by connecting axle, fixed stop is equipped with several and is used to limit the entad arm that refuse rotates with the draining fan, waste water flows out from draining fan leaf gap, when refuses such as leftovers, dish leaf are arranged in the water, starter motor then, the draining fan is discharged the refuse chopping.Obviously, there is following defective in this dredging device:

1. waste water can only flow out from draining fan leaf gap, and it is unimpeded that current are owed;

2. as long as when containing refuse such as leftovers, dish in the waste water, all must starter motor, otherwise occur easily stopping up;

To big refuse as mashed potato, large stretch of dish leaf etc. because the existence of fixed stop hoop heart wall can't enter the draining fan, the entad arm of this moment only plays the filter screen effect; Tiny refuse such as leftovers can pass through entad arm, but the little refuse of this class is then followed the rotation synchronously of knive-edge blade do under draining fan centrifugal action, be difficult to be shredded; So sizeable refuse is only arranged, it was not rotated by entad arm restriction not only but also can constantly contact the knive-edge blade time, could have been shredded.As seen the practicality of this dredging device is not good enough.

The object of the present invention is to provide a kind of practical electric dredger for washing sink, the draining grid are set around the dredging device cavity, and arrange that numerous static blades make full use of the rotation and the rolling of refuse, allow quiet blade and moving knife sword together refuse effectively be cut pulverizing, refuse for middle small size, need not starter motor, utilize this refuse can shred with respect to the motion of quiet blade, for the refuse of larger volume as mashed potato etc., starter motor then, utilize centrifugal force to quicken its rotation and rolling and moving, the comprehensive function of quiet blade with its quick chopping, thereby guarantees that waste pipe is unblocked.

Purpose of the present invention adopts following technical measures to realize:

1. at the guide pipe inwall guiding rib is set, makes waste water and refuse rotate and roll, be used to increase refuse the speed of related movement of quiet blade and both are in contact with one another chance;

2. at the inboard water flowing grid that contain water flowing grid hole and quiet blade that are provided with of cavity, the waste water major part is discharged from the grid hole, quiet blade quantity reaches more than 20, and refuse moves in face of the edge of a knife, and under the condition of starter motor not, these quiet blades also have the function of chopping refuse;

3. during starter motor, guiding rib, grid hole, centrifugal force, moving knife sword, quiet blade have a positive effect jointly, make big and small refuse all be close to numerous quiet blades and make rapid movement, this moment quiet blade effect much larger than the effect of moving knife sword, so can apace refuse be pulverized,

Below in conjunction with description of drawings, be described in detail the particular content of this programme.

The drawing explanation:

Fig. 1 is the structural representation of this electric dredger for washing sink.

Fig. 2 is the MM sectional view of Fig. 1.

Fig. 3 is the NN view profile of Fig. 1.

Fig. 4 is a water flowing grid partial perspective view of containing grid hole and quiet blade.

Fig. 5 is the structural representation of rotating disk and moving knife fork.

A kind of electric dredger for washing sink comprises motor, rotating disk, and cavity, the moving knife sword, its Feature is this dredge electricity guide pipe 1, cavity 2, motor 3, rotating disk 4, nut 5, moving knife Sword A, consist of with the draining bars 6 of quiet blade B, wherein guide pipe 1 inwall is provided with the helical form guiding Muscle 11, the upper end is connected with the kitchen sink port part by joint, and cavity 2 is cylindric, and with Outlet pipe is integrated, and its upper inside wall is provided with several vertical muscle 21, and sealing is arranged in its upper end Adopt screw to be fixedly connected with guide pipe 1 behind the ring, the bottom is fixedly connected with motor 3, rotating disk 4 Flatly be arranged in cavity 2 interior being fixed on by nut 5 and be provided with in externally threaded motor 3 rotating shafts, Moving knife sword A is arranged on the rotating disk 4, and draining bars 6 is provided with several grid hole that is in tilted layout and quiet cuttves Sword B is stamped to form by metallic plate, is arranged in vertical muscle 21 inboards after curling.

Above-mentioned helical form guiding rib 11 its helical angles are 45 °～60 °, quiet blade B its towards with Rotating disk 4 switched in opposite, rotating disk 4 are provided with the apopore that several apertures are 3～5mm, draining bars Arrange on 6 that the grid hole and the quiet blade B that tilt respectively are 20～32, the long 25～30mm in each grid hole, Wide 4mm, gradient is 15 °～20 °. Outlet pipe connects by the U-bend of joint and deodorization Connect.

With prior art relatively, this programme has the following advantages:

1. the waste water major part is discharged from the grid hole, is beneficial in Quick drainage and the water refuse and is close to quiet cutter Sword B motion is particularly suitable for the wastewater and waste materials from large-scale kitchen sink is processed.

2. around cavity 2, arrange from many quiet blade B, add 11 pairs of wastewater and waste materials of guiding rib Guide effect, make refuse rotate and roll along quiet blade B, though starter motor 3 not, rotating disk 4 A remains static with the moving knife sword, and quiet blade B also has the cutting crushing function to refuse, therefore Can start less motor and save power consumption. And existing dredge does not have quiet blade B, does not have this The cutting crushing function.

3. starter motor 3 then when wanting to contain in the waste water refuse of a large amount of refuses, particularly bulk, Guiding rib 11, grid hole, quiet blade B, rotating disk 4, moving knife sword A have a positive effect jointly at this moment, Especially rotating disk 4 gives centrifugal force to wastewater and waste materials, has accelerated refuse to quiet blade B relative motion Speed, waste water throws away from grid rapidly, has further improved quiet blade B refuse cutting is pulverized Speed, the cutting grindability of quiet blade B is much larger than moving knife sword A, visible this programme is than existing Technology is more advantageous.
